Yes, I believe everyone is willing to sell their data for money, and without you realizing it you have also sold your data to Google, Facebook or other social media where they don't even give you money directly, but they are the ones who get money from the data you send. .
The level of data sensitivity is really complicated, even poor people would be better off selling their data than not eating for a few days. That's why some people feel their data is more important, and some think that eating is more important. You cannot judge unilaterally, because everyone has different levels of needs.
I think it's not about that. It is not the same as Facebook or Google knowing that you prefer to buy an AMD GPU instead of an Nvidia one, or your real name and address, or that some company tries to scan your iris with the promise of deleting that information, which is a lie. There are several ways to prevent Google, for example, from having our data. It is also 100% effective and simple, not using any of Google's products (something that the world's population has become accustomed to for 26 years). Surely there will be people who will say that this is impossible, but it is perfectly possible, we just have to look for solutions.
For many years there have been multiple alternatives to Google (also Facebook, X, Gmail, Instagram etc.) that meet the standards, but people prefer to continue using what they already know and know how to use, even if it costs them their privacy. The learning curve is not difficult, nor is it necessary to have advanced technical knowledge, it is all a question of convenience versus privacy.
